I'm starting on java development. Why is this error happening?
I made a program to print big numbers using the scanner to select those numbers, but I'm getting an error every time I try to compile it
When I try to compile this program, the cmd promt outputs this:import java.util.*; public class Numbers{ public static void main(String[] args){ int num1, num2, num3, num4, num5, num6, num7, num8, num9, num10, quantity; Scanner sc = new Scanner(System.in); String[][]/*[Y][X]*/ bigNums = { { /*bigNums[0][0]*/ " ", /*bigNums[0][1]*/ " ", /*bigNums[0][2]*/ " ,pP´´Yq.
